PURPOSE: The goal of this study was to evaluate perioperative and mid-term results of coronary artery bypass grafting (CABG) in patients with end-stage renal disease (ESRD). METHODS: Thirty-five consecutive dialysis patients who required CABG over a 5-year period were investigated retrospectively. RESULTS: Mean patient age was 62.5+/-11.5 years. The mean number of diseased vessels was 2.3W0.8. Off-pump CABG (OPCAB) was performed in 12 patients. The mean number of anastomoses per patient was 2.5+/-1.1. The perioperative mortality was 5.7%, and the average duration of hospitalization was 25.3+/-13.4 days. Overall 5-year survival rates were 63.7%. The cardiac-related 5-year survival rate was 89.3%, and the cardiac event-free rate was 51.7%. Multivariate analysis failed to identify any significant prognosticators for perioperative or long-term outcomes. The morbidity rate was significantly lower in patients undergoing OPCAB than in patients undergoing conventional CABG (8.3 vs. 47.8%; p=0.03). Perioperative mortality in the OPCAB group was 0%, and the average duration of hospitalization was shorter in the OPCAB group than in the conventional CABG group (19.7 days vs. 28.5 days; p=0.1). CONCLUSION: In the context of coronary artery bypass surgery, OPCAB produced better outcomes than conventional CABG procedure in patients undergoing chronic dialysis. Further-more, OPCAB procedure seems to offer a greater benefit to dialysis patients than non-dialysis patients.
